ENVELOP.

Specification of Letters Patent. Patented June 22, 1920.

Application filed September 27, 1919. Serial No. 326,907.

especially serviceable in the railroad business for carrying messages from station to station, or other places. y

As a suggestive embodiment of'this lnvention, the accompanying drawing exhibits Figure 1, a plan view of the present inventlon;

Fig. 2, a rear vlew thereof; and m Fig. 3, a fragmentary View of the upper face portion, with flap extended outwardly, of the envelop after being twice used.

The envelop body, in the present instance,

may be formed, as is. usual, with a front face 5, a rear face 6, and sealing flap 7. This latter part is speciallyformed, however, by being perforated as at 8 from each end toward the center, as shown in Fig. 2, and having a plurality of slits, perforations, or cuts 9, arranged transversely of the perforations 8, all extendin toward the flap edae so as to provide in e ect separable flap sec- I tions, each designated aslO. According to this construction, each end of the flap is provided with an equal numberof sections 10, a widened section 11' remaining in the center, as shown. All of the flap sections are suitably gummed so that any one or more of them may be causedto adhere to the rear side of the envelop body for the purpose of providing a seal. e

As an aid to the use of this envelop,,certain directions may be printedon its face,

as, for instance, is shown in Fig. 1. In ad dition, other spaces may be marked off, each adapted to receive the address to which the envelop is to be forwarded. -I have shown from the envelop. followed when theenvelop is used for for- I being used on this occasion.

six such spaces marked off, corresponding to one-half the number of detachable sections provided on the flap, these sections be- 7 ing numbered in duplicate commencing at the flap ends.

The first time that the present envelop is to be used, space number 1 will receive the proper address marking, and the end seals similarly numbered will be adhered to the rear side of theenvelop, thus providing a seal for its contents. Upon delivery, the

envelop will be opened by tearing the flap around the two sectlons numbered 1, thus leaving these sections adhered to the body,

but permitting the remainder of the flap toopen up for the removal of the contents A similar procedure is warding matter to the second addressee, the address space and flap sections numbered 2 When the envelop has been again opened by tearing ofi the sections numbered 2, the flap will present an appearance such as is shown in Fig. 3. In this manner the envelop may be used over and over again until the address spaces and gummed flap sections are used up, at which time the envelop will have served its usefulness.

I claim:

An envelop having a closure flap which is perforated from its ends toward the center, there being other cuts extended transversely from the perforations toward the flap edgeproviding a plurality of detachable flap sections each of which is gummed on its rear side for adhesion to the envelop body, the flap affording a closure for the envelop when the two sections thereof at opposite ends of the flap are adhered to the body and affording an opening for the'envelop when such two adhered sections are detached from the body, a plurality of closures being thereby provided each capable of being successively utilized, substantially as described.
